Add #rss command family with LLM tags and summaries (v0.20.0)

#rss subcommands on the command channel: help / add <url> <name> / remove <name> / tags / sources / get <name|#tag>. Sources are stored in a new rss_sources table in the existing MESH_DB_PATH file (second node:sqlite connection, case-insensitive names); feeds parsed with fast-xml-parser (RSS 2.0 + Atom); AI tags and headline summaries via injected LlmService.chat() with bounded maxTokens (50/200). CommandService gains prefix registration so one handler owns the whole #rss family while #ping stays an exact match; wired in CommandModule's factory — still no constructor-level cycle, no forwardRef. One dead feed does not sink a tag summary.
